Launched last week, the new MacBook Pros are powered by Intel's Haswell processor. Based on the posts, it's unclear whether the problem is in the hardware or the software. However, some users report receiving the following error message: "The USB device Apple Internal Keyboard / Trackpad (Port 5 of Hub at 0x14000000) may have caused a wake by issuing a remote wakeup (2)."

CNET contacted Apple for comment and will update the story with any further information.
